We're dividing 33428939 by 840 
We're looking to find how many times 840 goes into 33428939.

On to step 1:
When dividing 3 by 840, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 840

Step 2:
The number 840 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 840

On to step 3:
When dividing 334 by 840, we get 0 with a remainder of 334.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 334 to get 334.
Fetch the next digit (2) from the dividend, attach it to 334 and continue: 3342 / 840

Moving on to step 4:
3342 divided by 840 is 3 with a remainder of 822.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2520 from 3342 leaves us with 822.
Fetch the next digit (8) from the dividend, attach it to 822 and continue: 8228 / 840

Advancing to step 5:
If we divide 8228 by 840, we get 9 and a remainder of 668.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 7560 away from 8228, we end up with 668.
Fetch the next digit (9) from the dividend, attach it to 668 and continue: 6689 / 840

Moving on to step 6:
If we divide 6689 by 840, we get 7 and a remainder of 809.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
Subtract 5880 from 6689 to get 809.
Grab the next digit (3) from the dividend, add it to 809, then carry on: 8093 / 840

Going ahead to step 7:
When dividing 8093 by 840, we get 9 with a remainder of 533.
Write down 9 as next digit of the result. 
Result so far: 3979.0
Deduct 7560 from 8093 and we're left with 533.
Take the next digit (9) from the dividend and append it to 533, then repeat: 5339 / 840

Going ahead to step 8:
If we divide 5339 by 840, we get 6 and a remainder of 299.
The number 6 becomes the next digit in our result. 
Result so far: 39796.0
If we take 5040 away from 5339, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 9:
840 goes into 2990 3 times with a remainder of 470.
Write down 3 as next digit of the result. 
Result so far: 39796.3
Subtract 2520 from 2990 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 10:
If we divide 4700 by 840, we get 5 and a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 39796.35
The remainder is 500 after subtracting 4200 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
840 goes into 5000 5 times with a remainder of 800.
Put 5 as the next digit of the answer. 
Result so far: 39796.355
Subtracting 4200 from 5000 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 39796.355 and a remainder of 0.08.
